BS061 70:30 (R:T) Non-Polarizing Beamsplitter Cube; 0.5 inch 400-700nm
The BS061 is a 0.5 inch non-polarizing beamsplitter cube, designed for use in the 400-700nm wavelength range. This beamsplitter cube, offered by Thorlabs, is a high-quality optical component that features a 70:30 (R:T) beam splitting ratio, meaning it reflects 70% of the incident light and transmits 30%.
The cube's geometry is defined by a 0.5 inch (12.7mm) cube side, making it compatible with a wide range of optical systems. The BS061 is made from n-BK7 Schott glass, a material known for its excellent optical properties and broad usage in the field of optics.
The beamsplitter's coating is another notable feature. Both the front and back surfaces, as well as the left and right surfaces, are coated with Thorlabs' CBS BBAR400-700 coating. This anti-reflection coating enhances the performance of the beamsplitter by reducing unwanted reflections and increasing transmission. The hypotenuse surfaces are coated with THo 7030NBK7CBS40070 and THo CBS BBAR400-700 coatings, further optimizing its performance.
